Hi
thank you for your suggestion. I looked for a while on openldap.org and
didn't find the article you are mentioning. But, I found the article
"How to use I use TLS/SSL?" in the Faq-O-Matic which gave me some
answers.
I'm just testing OpenLDAP to get the know how and that's why I'm not
going to buy a "real" certificate.
Nevertheless, I'm still curious about de document you are talking about...

Pierre,

It was posted to the list just a few days before your email. I deleted it
soon after.
